OIL-BURNER.

Specification 0! Letters Patent.

Application filed May 7, 1917. Serial No. 167,080.

To all whom it may concern.

Be it known that I, WILLIAM G. HAMIL- ron, a citizen of the United States of America, residing at Cleburne, in the county of Johnson, State of Texas, have invented a certain new and useful Im rovement in Oil- Burners, of which the fol owing is a specifiration.

This invention relates to a new and useful design and improvement in a form of hydrocarbon burner designed for use in con nection with heating furnaces, kilns and other places where it is desirable to gain a substantial high temperature by combustion of heavy hydrocarbon oils of the non-volatile class. The burner disclosed in this specification has such a particular design as to enable it to give a substantially high blowing capacity which imparts a long blast of flame from the burner orifice into the fur nace or kiln. It is a purpose of this invention to provide a form of burner which may be mounted outside the furnace or boiler to be heated thereby leaving its parts exposed to the view of the fireman or operator which insures most efficient operation since the burner may be kept clean and in proper adjustment.

With the above and other objects in view the invention has relation to a certain design and arrangement of injection ports, an example of which is described in the followin: specification pointed out in the appended cl and illustrated in the accompanying drawing wherein,

The figure illustrates a longitudinal sectional view of the burner showing'arrangement of the several injection ports and burner orifice.

In the drawing the numeral 1 points out a substantially long tubular member of suitable diameter. The forward end 2 of the tube is reduced in size and adapted to be protruded into the fire box of a boiler or kiln and acts as the burner orifid e. The other extremity of the tubular member is rcducedto a cylindrical form 8. A tubular passage 4 is 'integrally formed with the burner member and concentrically formed therein with an upturned projecting exposed extremity in the form of a connecting port 5 provided on the outside thereof for connection with a suitable stcapi or compressed air pipe. A second tubu member 6 is contained within the burner tube and concentrically formed therein with a projectin extremity 7 which carries a screwthrea ed cap 8 provided with a'plurality of air receiving ports 9. An automatic air inlet valve 10 is operatively confined in the tube 6 7 for the burner.

Undergoing operation this burner will re celve its injection of fuel oil through the purpose of admitting air to the port 3 which fuel oil may be sprayed or atomized thereinto if desired. The volume of compressed air or steam introduced through the port 5 sets up a considerable movement of air or steam from the burner orifice 2, which in turn creates a considerable suction through the automatic air valve taking in the desired uantity of air to be co-mingled with the mixture. By the time the fuel has passed by each port 6 and 4 it will be thoroughly co-mingled with oxygen and steam and passes onward through the tube discharging at the orifice 2 as a thorough combustible mixture. The extremity of the tube or burner orifice 2 lying within the hot fire box will incidentally raise the combustible mixture to a high temperature setting up the proper combustion at theorifice 2. The draft of the burner set up by the steam or compressed air injection imparts considerable pressure to the combustible mixture discharged at the port 2 sulficient to give a tongue of fire which will pass far into the tire box. The quantity of oil and steam introduced into the burner will be regulated by suitable valves located in the pipes used for conveying the oil and steam to the burner. Such connections and valves having no direct relation to this individual burner, are not shown. With a battery of these burners arranged to inject their flames into a fire. box it is possible to obtain any desired temperature, and the burners are most economical in fuel consumption since their design enables the fireman to properly adjust the mixture down to where a minimum fo m it may come within the meaning of th. folmwing claim:

Claim: I In an oi' nurner, the combination with a cylindrical tube tapered at one end to form a burner orifice and reduced at the other end to form an inlet for oil. a pair of tubular connections formed in the cylindrical tube and extended into said tube where the ends interior of the device, and the other tubular thereof are open in the form of a nozzle and connection adaptable for use in connecting directed toward the burner orifice and conup with a steampr air pressure for creating 10 centric-ally arranged within said tube, and a blast at the burner orifice.

5 an automatic air valve contained within one In testimony whereof I hereunto affix my of the tubular members for the purpose of signature. feeding air in regulated quantities to the WM. G. HAMILTON.
